A search for "ledbat" in github doesn't find any reference, which is a shame. Apple are the only one with ledbat support in the kernel[0] afaik, and it's functionality that's sorely needed -- it's ridiculous that there's no way to say "data on this connection is not urgent, only give it bandwidth as long as it doesn't interfere with other connections". Some programs, e.g. rsync, let you limit bandwidth - but that's wasteful; I want this 2TB rsync job to be downloading at full speed at all time I'm not doing anything else.
[0] yes, this is userland, but it's for fuchsia, so "kernel functionality" as far as its users are concerned.
